altLeft Sets or retrieves a value that indicates the state of the left ALT key.
cancelBubble Sets or retrieves whether the current event should bubble up the hierarchy of event handlers.
clientX Sets or retrieves the x-coordinate of the mouse pointer's position relative to the client area of the window, excluding window decorations and scroll bars.
clientY Sets or retrieves the y-coordinate of the mouse pointer's position relative to the client area of the window, excluding window decorations and scroll bars.

Remarks

Creating custom code to enable the Paste command requires several steps.
Set the event object returnValue to false in the onbeforepaste event to enable the Paste shortcut menu item.
Cancel the default behavior of the browser by setting the event object returnValue to false in the onpaste event handler. This applies only to objects, such as the text box, that have a default behavior defined for them.
Specify a data format in which to paste the selection through the getData method of the clipboardData object.
Invoke the method in the onpaste event to execute custom paste code.

Example

This example uses the clipboardData object to implement custom editing functionality.

<HEAD>
<SCRIPT>
var sNewString = "new content associated with this object";
var sSave = "";
// Selects the text that is to be cut.
function fnLoad() {
var r = document.body.createTextRange();
r.findText(oSource.innerText);
r.select();
}
// Stores the text of the SPAN in a variable that is set
// to an empty string in the variable declaration above.
function fnBeforeCut() {
sSave = oSource.innerText;
event.returnValue = false;
}
// Associates the variable sNewString with the text being cut.
function fnCut() {
window.clipboardData.setData("Text", sNewString);
}
function fnBeforePaste() {
event.returnValue = false;
}
// The second parameter set in getData causes sNewString
// to be pasted into the text input. Passing no second
// parameter causes the SPAN text to be pasted instead.
function fnPaste() {
event.returnValue = false;
oTarget.value = window.clipboardData.getData("Text", sNewString);
}
</SCRIPT>
</HEAD>
<BODY onload="fnLoad()">
<SPAN ID="oSource"
onbeforecut="fnBeforeCut()"
oncut="fnCut()">Cut this Text</SPAN>
<INPUT ID="oTarget" TYPE="text" VALUE="Paste the Text Here"
